Answer is Right!
Answer is Wrong!
The correct answer is B. was.
Aashka was there before a week. This means that Aashka was in a particular place at a time in the past that is one week before the present time.
The other options are incorrect because:
- A. did does not make sense in this context.
- C. which is used to introduce a relative clause, which is not needed in this sentence.
- D. when is used to ask about the time of an event, which is not what is being asked in this sentence.
